Laura Robson, just over three months after winning the Wimbledon junior girls title, and receiving the kind of acclaim afforded Andy Murray and Tim Henman, steps out on to the WTA main tour for the first time today at the Fortis Championships in Luxembourg where she will face Iveta Benesova of the Czech Republic in front of a handful of fans.

It will all be a far cry from the hype of the All England Club, but the Australian-born Robson, 14, has always insisted that her ultimate aim is to become the best player in the world.

Robson has recently played in a number of senior events where she claimed victories over higher-ranked opponents, enabling her to attain her first world ranking of 550. Because of her age the number of professional tournaments she can play in will be restricted, a rule brought in when the WTA became concerned that there was a danger of burn-out among its younger players.

Annabel Croft, the last Briton to win the Wimbledon junior title 24 years ago, and lauded as potentially the next in a line of British women grand slam champions became so disenchanted with life on the tour that she retired at the age of 21.

Robson is keen to rise up the rankings as quickly as possible but for the time being she will mix senior and junior events. She said: "I now know I can play with the women players but they have got so much more experience, so I will just work my way into the women's tour because there is no rush at all."

Benesova, like Robson a left-hander, is ranked No42 in the world, and at 25 has already been a professional for 10 years, playing in 25 slams, although she has never gone beyond the last 32.

Robson received a wild card into the tournament, suggesting that the British junior is already playing at the level of a top-150 player.
